The paper discusses the development of an IBM PC based tool, for calculating train braking distances for various train classes on a rail network. There is discussion on current industry practice and the limitations of that practice, the concept of the tool itself, including the assumptions made, the strategy adopted to minimise the risk of incorrect calculations, and the results of adopting tha...

A further commercially available encryption package for the IBM PC is analysed, and a simple breaking program is described.

Binary-choice reactions are typically faster when the stimulus location corresponds with that of the response than when it does not. This advantage of spatial correspondence is known as the stimulus-response compatibility (SRC) effect when the mapping of stimulus location, as the relevant stimulus dimension, is varied to be compatible or incompatible with response location. It is called the Sim...

Fast improvement of web technologies have caused a problem of semantic integration between distributed applications. In this respect, sharing and distribution of information are of vital importance for ontologies. Ontologies may be improved by any independent association and still be used by another association. In case an association decides to use an ontology improved by another association, ...

PURPOSE Voltage-based device-tracking (VDT) systems are commonly used for tracking invasive devices in electrophysiological cardiac-arrhythmia therapy. During electrophysiological procedures, electro-anatomic mapping workstations provide guidance by integrating VDT location and intracardiac electrocardiogram information with X-ray, computerized tomography, ultrasound, and MR images. MR assists ...

in this paper we formulate and prove some xed and common xed pointtheorems for self-mappings de ned on complete lower transversal functionalprobabilistic spaces.

We extend the definition of algebraic entropy to endomorphisms of affine varieties. We calculate algebraic entropy of the action of elements of mapping class groups on various character varieties, and show that it is equal to a quantity we call the spectral radius, a generalization of the dilatation of a Pseudo-Anosov mapping class. Our calculations are compatible with all known calculations of...

Abstract. In body surface potential mapping, data conversion can be required whenever merging data sets taken by slightly different data acquisition systems. In this case, we face with a kind of conversion problem. This paper describes a method for solving the problem according to the least-square principle, so the datasets of physically different body surface potential mapping systems become c...
